What the Clear Film Marker is built to do
The Clear Film Marker is a UV laser marking system selected for thin plastic films that need careful handling and a crisp finish. It is suited to delicate packaging webs, technical films, labels on clear or lightly tinted plastics, and product codes that must stay readable after handling, folding or transport. Because the process is non contact, there is no blade wear and no ink smudging, which helps when you are working on material that can stretch, curl, or show heat marks easily.
In practical terms, this is the right choice when a conventional print method is too soft, too wet, or too rough for the film. The UV wavelength is used to mark at low thermal load, so the surface is altered with much less risk of warping compared with hotter processes. That makes it useful for converters, packaging teams, medical consumables, electronic component packaging and speciality film lines across Ekurhuleni and further afield.
- Designed for thin plastic film and other delicate polymer surfaces
- Permanent marking for logos, dates, batch codes and small text
- Fine control for light film where excess heat is a problem
- No consumable inks or ribbons to manage on the line
Film sizes, formats and marking options
We set up the Clear Film Marker around the size of the film web, the marking window and the amount of detail required. Some customers need short, neat marks on narrow rolls, while others need repeated marking across wider film moving at line speed. The system can be supplied with different working areas and mounted to suit the machine layout, the unwind and rewind positions, or a dedicated marking station with controlled feed.
Marking content can include fixed wording, serial numbers, QR codes, barcodes, ingredient text, compliance details, logos and pattern work. For clearer film jobs, the mark depth and contrast need to be balanced carefully so the result is visible without overworking the material. Refilwe Mahlangu often assists with sample testing for this reason, because the right setting on a 25 micron film can be very different from what works on a thicker sheet.
- Suitable for narrow web and wider film formats
- Fixed text, sequential numbering and traceability codes
- Fine graphics and small character marking for branding
- Options for offline sample testing before full installation
Where it suits best on production floor and packing lines
This product suits businesses that need dependable marking on film used in packaging, medical packing, electronics, laboratory supply, personal care wraps and technical sleeves. It is also useful where a municipal or customer inspection requires clear traceability, legible dates or batch codes that do not fade in storage. In the Gauteng industrial belt, many sites ask for a marking solution that can cope with dust, shift changes and load-shedding interruptions without upsetting the film path once power is restored.
Jet Park, Boksburg and surrounding areas such as Germiston, Kempton Park, Benoni, Alberton, Midrand and Pretoria often have mixed line setups, so the marker is usually planned to fit into existing handling equipment rather than forcing a full line rebuild. It also works well where humidity or temperature changes affect film tension, because the focus is on controlled marking rather than physical contact with the material.

- Medical and laboratory consumables
- Electronics and component packing
- Speciality plastic film and sleeve production
Installation, power and support requirements
The Clear Film Marker is installed according to the film route, the available mounting space and the operator access needed for safe running. Our team can assist with site demos, fixture design, line integration and full machine installation nationwide. Naledi Mokoena coordinates the practical side of the job, while Thabo Khumalo handles field installation work where the machine must tie in neatly with an existing line. We also provide operator training so the crew knows how to start up, pause, check focus and confirm job files before production begins.
Power needs depend on the final configuration, but the system is typically set up for standard industrial electrical supply and a stable connection with proper earthing. On sites where power dips are common, we advise checking backup capacity and the sequence in which the line recovers after outages. No process gas is normally required for the marking head itself, although some installations may need air for associated machine functions or line guards. Good extraction is recommended where the film or surrounding process may release fumes from surface treatment, especially in enclosed packing rooms.
- Site demos available before purchase or line conversion
- Installation matched to your film feed and operator space
- Standard industrial electrical supply with proper earthing
- Usually no process gas required for the laser marking head
Care, servicing and keeping the mark consistent
As with any precision marking system, consistency comes from basic care and regular checks. Keep the optics clean, keep the film path aligned, and make sure the working area stays free of dust and trim waste. In dry inland conditions, dust can settle quickly on covers and lenses, while at coastal or humid sites the issue is often condensation and handling marks on the film itself. A simple cleaning routine helps the machine hold its setting and reduces avoidable downtime.
Preventive maintenance is worthwhile if the line runs daily or if you have a small team managing several machines. Priya Naidoo helps organise service visits, spares supply and breakdown repairs so the system does not sit idle when a sensor, cable or mount needs attention. We also handle software setup and process optimisation when the job changes from one film type to another. If the mark starts to look faint, uneven or shifted, it is usually a sign that focus, feed speed or fixture alignment needs review rather than a fault with the film itself.
- Clean optics and covers on a set schedule
- Check alignment after changeovers or transport
- Use preventive maintenance on high duty cycle lines
- Review focus, speed and tension when results change
What to confirm before you order
Before ordering the Clear Film Marker, it helps to confirm the exact film material, thickness and finish. Thin films behave very differently depending on whether they are clear, white, printed, metallised or lightly textured. We also need to know the production speed, the available space around the line, whether the film is flat or moving over a roller, and what type of code or image must appear on each mark. Those details guide the sample testing and let us match the marking window to the real job, not just the drawing on paper.
Riaan Pretorius and the UV Laser team work through these points with customers from Jet Park and across South Africa, including installations in industrial sites where access is tight and stoppages are costly. The more precise the job brief, the better the result on day one and the less adjustment needed after commissioning. If your film is part of a regulated product line, include any required legibility rules, batch format or customer spec so the setup can be checked properly.
